What is this Vintage Computer T-Shirt talking About?

I love the imagery in this t-shirt, but there is so much going on here, I have no idea what it is about. Do Massachusetts Lawyers need a computer as fast as the Condcorde? Do they book travel on the Condcorde on their computer? Anyone have a guess?

But the plane is BREAKING the computer. Plus, Concord, MA is spelled differently than the Concorde. In addition, why would a computer repair shop cater only to law firms? I realize this is Massachusetts, but Concord is only so big.
